Compatibility and Installation
The Oberdorfer 109MB-10J36BJ is specified for compatible 230V AC, 50/60 Hz single-phase circulation systems. Confirm electrical supply, motor wiring, circuit protection, 1/2-inch NPT plumbing, fluid compatibility, required operating flow, system head, liquid temperature, and installation space before ordering. This international-spec 230V model is not a direct replacement for a 115V pump.
the listed specifications do not state self-priming capability; use flooded suction unless manufacturer documentation approves another installation arrangement. Actual flow varies with total dynamic head, plumbing size and length, fittings, restrictions, fluid conditions, and electrical supply. Do not exceed the 200 degrees F continuous liquid-temperature rating. Follow manufacturer instructions and qualified electrical and plumbing practices for mounting, wiring, bonding, and commissioning.
